To all wiz/m it may con/cern:

Be itknown that we, J oHN ELvvooD LAM- BORN and Ross RIoKARDs, of Dixon, in the county of Solano and State of California, have invented certain new and useful Improvements in VVheel-Plows; and we do hereby declare the following to be a full, clear, and exactdescription of the invention,such as will enable others skilled in the art to which it pertains to make and. use it, reference being had to the accompanying drawings, which form part of this speciiication.

Our invention relates to an improvement in 'wheel-plows; and it"consists in, first, a circular frame, a ring surroundingthis circular frame and having a limited play thereon, and a plow beam or beams secured to this ring and moving therewith; second, a circular frame, two independent axes journaled in separate bearings thereon, and levers for raisv ing and lowering the wheels placed upon the axles, combined with a ring which surrounds the circular frame, the plow beam or beams secured to the ring, and a lever for locking the ring and the beams attached thereto in a line with the forward-draft of the machine, as will be more fully described hereinafter.

` rlhe objects of our invention are to provide a wheel-plow which will turn a square corner, and thus leave no ground unplowed, and to provide a walking wheel-plow, upon which a single beam or a gang of beams can be used equally as well.

Figure 1 is a plan view of a plow which embodies our invention. Fig. 2 is an inverted view of the same. Fig. 3 is a side elevation.

A represents a circular frame, which has secured to its inneropposite sides, in any suitable manner, two boxes or bearings B, in which the two separate cranked axes C are journaled. These boxes B have plates, wings, or extensions D extending from opposite ends and which form supports for the ring E to rest upon. Secured to the top of the circular frame A, in any suitable manner, are the plates G, which extend over the top of the ring E, and thus prevent it from rising above the circular frame or becoming displaced therefrom in any manner. Extending across the top of the circular frame is the double rack H, which has its rear end secured to the top of the circular frame A, and this end is extended beyond the rear edge of the circular frame, so as to catch over the top of the ring E and also assist in holding it down in position. The front end of the rack is pivoted inside of the circular frame below its upper edge, as shown, so as not to interfere with the lever by which the tongue or draft-bar is moved laterally. cranked axles C are the two levers I, which engage with opposite sides of the rack I-I and hold the axles in any desired position. By means of these levers the cranked axles and wheels can be adjusted independently of each other in the Well-known manner.

Secured rigidly to the two The ring E tits loosely around the circular 4 frame A, as shown, so as to have a movement through about one-quarter of a circle, and to this ring are secured either a single beam ora number of beams, which are braced together as here shown', as may be desired. lVhether one or a gang of beams are used the operation of the parts is just as perfect. In order to lock the ring in position, so that the beam or beams secured thereto will follow in a straight line with the forward draft of the machine, a notch is cut in the tops of both the circular frame and the ring, and when the lever J is dropped into this notch the ring is locked in position. When the end of the row or corner of the field is reached, this lever J is raised out of the notch and then the team is turned through a quarter of a'circle, the ring remaining stationary and the circular frame turning freely inside of it, and when the turn has been made the pressure of the plows against the ground will cause the ring to turn upon the circular frame until the beams are again brought in the line with the machine,` when the lever K again drops into the notch and locks the ring rigidly in position. In turning the wheels and circular frame around without turning the beams at the same time there is no strain brought upon the wheels or the axles or the point of the pull-rod or tongue. The pull-rod or tongue is loosely fastened to the under edge of the rear side of the circular frame and extends through a supportingloop O upon the front of the frame and has ASo IOO

the lower end of the lever P connected therey moves lthe pull-rod or tongue laterally, so as to cause the plow to plow wider or narrower furrows, as maybe desired. The plate through which the rear end of the tongue or pull-rod passes or to which it is secured has its rear end to project backward under the ring and serves as a support therefor.

A wheel plow constructed as above descr1bed,whether provided with a single beam or a gang of them, will turn eitherto the right or left, thus leaving no land unplowed, and prevents upsetting or springing the beams,

breaking wheels, springing' the axles, or

springing the pullfrod or tongue. By means of the levers, which raise and lower the wheels, the plow can be made to run shallow or deep; or they can be raised above the ground, so as notto be brought into operation ghlidle the plow is being moved to or from the Having thus described our invention, we claimal. The ,circular frame and `the lcranked axles and wheelstjupon which itis supported, combined with the ring to which the beam or beamsare secured',whereby lth'ewheels can be turned through a portion' of a circle without affecting the beams, substantially as shown.

2. The circular frame, the cranked axle, and the wheels, combined with the levers secured to the axles, the ring, and the beam or beams secured thereto, substantially as described.

3. The circular frame, axles upon which the frame is supported, and the driving-Wheels placed upon the axles, combined with the ring, the beam or beams secured to the ring, levers secured'to the axle, and a locking device for locking the ring in position, substantially as set forth.

4. In a wheel-plow, a circular frame that is mounted upon wheels and which has an independent turning movement through a portion of a circle by means of the tongue or pullrod, combined with a ring which 4has a turning movement upon the frame, and the beam or beams secured to the ring, substantially as specified.

In testimony whereofwe affix our signatures in presence of two witnesses.
